WAGON-BRAKE.

SPECIFICATION forming part of Letters Patent No. 310,174, dated January 6, 1885,

Application filed August 21, 1884.

To all whom, it may concern:

Be it known that I, BERTIIOLD Boson, a citizen of the United States, residing at Burlington, in the county of Des Moines and State of Iowa, have invented a new and useful VVagon-Brake, of which the following is a specification.

My invention relates to improvements in wagon brakes in which a brake-bar in one piece for both wheels operates in conjunction with levers; and the objects of my improvements are to provide a brake or look which will do the work more effectually than it is done by any brake now in use, and to furnish a brake very simple in construction and easily applied. I attain these objects by the mechanism illustrated in the accompanying drawings, in which Figure l is a bottom plan of a wagon with the brake attached. Fig. 2 is a side view of a wagon, showing the connection of the operating lever with the brake mechanism.

Similar letters refer to similar parts throughout the several views.

Fig. 1 represents a view of the wagon-bed from below, with the brake attached, in which A represents the brake-bar, having brakeshoes to and a. B and B are levers pivoted in orificeso r or u and 0 r and u by means of bolts or otherwise upon cross -bar O, which cross-bar is attached in any suitable manner to the frame or the bed of the wagon. Levers B and B, by means of rods g and q at (Z and (1, connect with the brakebar A. b and I) are small bars, jointed, respectively, at one end to B and B, and in their other end to rod D. Rod D runs underneath and along the middle, or may run to either side of the wagonbed, from the brake to the front of the wagon, 0 and is supported by guides 9 and 19. At 6 (N0 model.)

so that arm E will move freely to and fro in the dentated guide M, fastened to the front end of the wagon box, and may be set into any of the interdental spaces. Arm E has handle m.

To the respective sides of the wagon-box, between the front and hind wheels, are the guides 95 and x, for the purpose of holding brake-bar A.

The operation of my invention is as follows: XVhen arm E rests in guide M and close to the wagon -boX, the brake is loose or not in use. If the brake be used, arm E is pushed along the guide M, whereby rod D, connected at c with said arm, is drawn forward, and rod D, by means of bars I) and I), also draws the arms of levers Band B, connected therewith, forward, which throws the other arms of B and B back, whereby, by means of rods 1 and q, the brake-bar A,with its brake-shoes a and a, is pressed against the wheels, thus holding the wheels in a firm grasp.

The object of having the holes 0 r or a and 0 1" or it is to be able to adjust the brake properly in order to get more or less power, as it may be desired.

hat I claim, and desire to secure by Letters Patent, is

In a wagon-brake, the brake'bar A, having brake-shoes a. and a, and sliding in guides 00 and 00, in combination with rods q and q, levers B and B, bars b and 1), rod D, arm E,

projection 7c, and dentated guide M, substan- 7
